Hi everyone, I'm currently designing a polyphonic synth for my dissertation at university. I have 4 input (possibly 8) controls that need to be distributed to 8 voice cards, so I was thinking of using digital potentiometers. I saw that only 2 digital potentiometers can be used at a time with an Arduino, but I was wondering if there's any way 32 (or possibly 64) potentiometers could be used. Is there any way the signal could be multiplexed so identical sets of the 4 inputs could be sent to each of the 8 cards?
Thanks for any help you can give
